cessory inside elevation applied to a rim ,ing on an lenlargedscale the details of con- 60. 'structlon.

The vehicle wheel rim 1 0 isone'ofiordi nary construction of the so-called quick detachable type',and has at. one edge a retaining clenclier. ring. or flange 11 which may .65,

be separate from: or-integralwith. the rim proper. In the. presentinstance, it isshown as a separate element. Along the other. edge of the rim the latter is-de-formed inwardly so as to provide an internal-rib 12 present:

ing agroove 13 on the outer faceof the rim for.--the reoeptionof the customary locking: ring, the edge .1 1. of the rim being; substan 'tially in register-with the-main outer; face vof theariml With rims of this type it is in part this groove which renders itha-rd "to remove the tirecasing, such as one of. thetlre, tends-to enter or occupy-such groove,

clenche'r type 15 shownin the drawing.

more on less difiicultto apply a tire-casing laterally or sidewise to=a, rim Whether of the solid or divided style, particularly iflthe rim happens to be, somewhat oversize or'the.

tire-casing is slightly underslze, and 1t 1sto facilitate andaidl'n removmgthe tirecasingfromthe rim-or mounting it on the rim thatthe new appliance is deslgned.

Such, appha-nce'or accessory comprises a thin, more or less flexible,longitudinallyc r d metal member 16- which extends only partially around thecircumference of the rim, leaving; a gap between its two. ends, which are connected togetherby. a coil contractile spring 1 7- whoseterminal hooks 18 and 19 engage apertures in'the end portions, of the part 16. Thus, this comparativelyfiexible member, whose ends are yieldin' ly connected together by the spring, is capable *of a limited degreeof expansion-and oontraction, which adapts it for employment with rims and" tires of different sizes.

.As is clearly shown in both figures of the drawing and on a larger scale in Fig.2, such member. 16 is externally, transversely convex, the portion thereof extending outs wardly beyond the edge of the rimbonverging somewhat 7 toward its axis, and; .to. a. lesser. degree: that portion of the-member; over the rimcurves inwardlyslightly and is 11.0,

of such a dimension as to practically cover or overlie the groove 13. I Internally this expanslble and contractible member has a lon- "gitudinal groove adapted to receive and fit over the edge portion lat of the rim, and,

due to the two side walls or shoulders of follows Assuming that it is desired to removethe casing 15 from the rim 10, the olencher-holding flange and cooperating locking-ring (not shown), are removed from one side of the rim in the usual way, the locking-ring being thereby holding the member properlyin position, the contraotible action of spring 17 holding the attachment firmly and snuglyin place over the rim. It will be observed that the inner portion of this member closes the mouth of the groove 13, being curved slightly inwardly, and thus in drawing off or demounting the tire-casing it is impossible for its inner edge portion to become caught in the groove with danger of injury, and the same also applies to the flap within thecasing. In thus withdrawing the casing the member lfi cannotbe dislodged, being held firmly in position by reason. of the presence of the groove 20. In thus demountingthe casing that portion directly opposite the valve stem is first lifted or pulled off and then the remainder of the casing is re? moved in the proper direction, as is usual, to draw the valve-stem out through its aperture in the rim. i 7

If it is desired to mount abusing on a rim of this-type,using the improved appliance, the casing is partially placed overv the rim with the valve stem through its hole andv then the remainder of the casing is pushed sidewise over the rim, being guided into proper place by the flaring outer portion of the member 16, which guides it on to, the rim and over the groove 13. In other words, this appliance acts somewhat on the principle of a, shoe-her; The casing having been positioned on the rim, the appliance is readily taken off without interference with the tire or any of its parts, whereupon the remaining elements of therim may be put in place in the usual manner. 7 a V V lVhereas I have illustrated this device as particularly applicable for use with a rim of thetype illustrated, it is to be understood that the invention is not limited and restricted to any particular use'and may be advantageously employed with rims of various shapesand sizes. It is also to be understood that many minor mechanical changes may be incorporated in the appliance without departure from the substance and essence of the invention and without the sacrifice of any of its substantial benefits and advantages. a
